"Think globally, act locally"

Run your GitHub Actions locally! Why would you want to do this? Two reasons:

Check out the GitHub Local Actions Visual Studio Code extension which allows you to leverage the power of act to run and test workflows locally without leaving your editor.

When you run act it reads in your GitHub Actions from .github/workflows/ and determines the set of actions that need to be run. It uses the Docker API to either pull or build the necessary images, as defined in your workflow files and finally determines the execution path based on the dependencies that were defined. Once it has the execution path, it then uses the Docker API to run containers for each action based on the images prepared earlier. The environment variables and filesystem are all configured to match what GitHub provides.

Let's see it in action with a sample repo!

Please look at the act user guide for more documentation.
